Helium has a nuclear charge of +2 and 2 electrons in a 1s orbital. Hydrogen has a nuclear charge of +1 and just one electron in a 1s orbital. The extra charge on the nuclees means that the electrons in He are more tightly bound than in hydrogen thuis reflected in the ionization energy of 2372 kJ/mol for He and about 1312 kJ/mol for hydrogen. For helium t the "outer shell" is full, a "stable " configuration.

How is the nucleus of the hydrogen atom different from the nucleus of the helium atoms?
The hydrogen nucleus has a single proton. The helium nucleus has two protons and one or two neutrons.
How does the ground state electron configuration of the hydrogen atom differ from that of a ground state helium atom?
The ground state electron configuration of the hydrogen atom is 1s1, and for helium it is 1s2.

the number of helium and hydrogen atoms is the same
Why is it impossible for helium or hydrogen to emit an alpha particle?
Because an alpha particle is bigger than a helium or hydrogen atom.

Where does the sun gets energy from and goes to light and heat?
The sun uses nuclear fusion to produce light and energy. the process is relatively complicated but simplified it looks something like this. step 1: hydrogen atom + hydrogen atom = deutrerium atom (an isotope of hydrogen (one extra neutron)) + positron + neutrino step 2: Deutrerium atom + hydrogen atom = helium 3 (an isotope of Helium (missing one neutron)) + energy step 3: helium 3 atom + helium 3 atom = helium atom + hydrogen atom + hydrogen atom + energy.
Number of hydrogen atom fuse to form helium atom?
2 hydrogen atoms
How does the ground state electron configuration of the hydrogen atom differ from that of a ground state helium atom?
The ground state electron configuration of the hydrogen atom is 1s1, and for helium it is 1s2.
Does helium have hydrogen in it?
No. Helium and Hydrogen are two different elements.
An atom of helium has a mass about four times greater than that of an atom of hydrogen Which choice makes the correct comparison of the relative numbers of helium and hydrogen atoms in equal masses o?
the number of helium and hydrogen atoms is the same
Is an alpha particle identical to the nucleus of a hydrogen atom?
No, it is identical to that of a helium atom.
Why is it impossible for helium or hydrogen to emit an alpha particle?
Because an alpha particle is bigger than a helium or hydrogen atom.
Which atom is the heaviest helium uranium lead iron Hydrogen?
Uranium atom is the heaviest.
How does hydrogen occur?
When two hydrogen atoms fuse to become one helium atom.
